NEw YoRK AGRICULTURAL EXPERIMENT STATION. 357 
Summary of results— From the above table it will be seen that 
no injuries attended the dipping of the trees in kerosene emulsion 
or miscible oil in the proportions as given. The trees having their 
tops only immersed in the lime-sulphur wash likewise sustained no 
harm, while of the trees which were completely wetted with this 
spray, 133 were killed outright and 2 lived to make a very poor 
growth. The trees that were fumigated showed no appreciable in- 
juries and made a normal growth. All of the thirty checks grew 
satisfactorily, without evidences of injuries by the handling and 
transplanting. 
EXPERIMENT VIII. 
BARTLETT PEARS DIPPED IN SULPHUR WASH FOR DIFFERENT TIME 
PERIODS. 
In this experiment there were 120 2-year-old Bartlett pears di- 
vided into six lots of 20 trees. Each lot was equally divided, and 
half the trees were wholly immersed and the remaining ones were 
dipped, with the exception of the roots. The time periods were as 
follows :— 
Lot I, instantaneous immersion, Lot II, dipped for one minute, 
Lot III, two minutes, Lot IV, three minutes, Lot V, five minutes, 
Lot VI, ten minutes. The standard lime-sulphur wash, with a 
temperature of 60° F., was used. 
Results on trees.— With few slight exceptions, no injuries were 
sustained by any of the trees preceding Lot V. In Lot V, six 
trees that were completely immersed, died; and in Lot VI two trees 
similarly treated were killed. There were no losses among the 
checks. 
EXPERIMENT IX. 
MANN APPLES DIPPED IN SULPHUR WASH FOR DIFFERENT TIME 
PERIODS. 
For this experiment 290 3-year-old Mann apples were used. 
The trees had been kept through the winter in cold storage and 
were not removed until April 27, when they were dipped. At the 
time of treatment the trees were dormant, with the bark and roots 
dry. For dipping, the trees were divided into six lots as follows: 
Lot I, 140 trees, instantaneous immersion, Lot IJ, 30 trees, immer- 
sion for one minute, Lot III, 30 trees, two minutes, Lot IV, 30 trees, 
four minutes, Lot V, 30 trees, five minutes, and Lot VI, 30 trees, 
ten minutes. Each of the above lots was divided into three parts; 
and for the treatment the trees in part I had the tops only dipped;
